In the present study, nanoporous material type MCM-41 was prepared by the sol-gel technique and was used as a carrier for prednisolone (PRD) drug delivery. The structural properties of mesoporous were fully characterized by X-ray diffraction (XRD), N2 adsorption /desorption and Fourier-transform infrared (FTIR). The mass transfer in term of adsorption process (loading) and desorption process (releasing) properties were investigated. The maximum drug loading efficiency was equal to 38% and 47.5% at different concentrations. The PRD released was prudently studied in water media of pH 6.8 simulated body fluid (SBF) in according to "United State Pharmacopeia (USP38)". The results proved that the release of prednisolone from MCM-41 was (69.4%) after 24 hr. The data of the released PRD was found to be submitted to a Korsmeyer–Peppas model.
Several problems have emerged as a result of urban expansion or the connection of urban areas with rural areas. This process has led to the urbanization of rural areas, and to have overlapping edges and margins of areas, which were outside the basic design of the city. Accordingly, the present research assumes that the accelerating growth of Baghdad population has contributed significantly to the process of unplanned urbanization. Thus, the study aims to examine the factors that have led to an increase of urban sprawl at the expense of the agricultural land. The study has thus adopted the descriptive, analytical, and historical approaches relying on the simple linear regression method to predict the phenomenon of urban expansion and its

Alfonso Sastre escribió La Sangre y la ceniza, su primera obra dentro de la llamada “Tragedia Compleja” en los primeros años de la década de los sesenta, pero la primera edición no apareció hasta el año 1967 y fue en lengua italiana. Por causa de la censura la obra estuvo prohibida a lo largo de muchos años, finalmente su primera edición en castellano apareció en el número 1 de la revista Pipirijaina, en octubre del año 1976. El estreno tuvo lugar en el Teatro Villarroel de Barcelona en enero de 1977, a cargo del Colectivo de Teatro ‹‹El Búho›› el cual realizó con este espectáculo una gira por toda España y más tarde lo ha representado en los Festivales Internacionales de T
